Ubuntu Networking :: Internet Slow After Upgrade To Kernel 2.6.32-24?

Jul 27, 2010

I have just built a PC based around an i7-860 and Asus P7P55D mobo. It was running fine until the big update that happened today and now the internet is like treacle. I did the same update to my other (different hardware) PC and all is fine with it.

When I load the earlier 2.6.32-21 kernel instead of 2.6.32-24, the new system works as it should and the Internet is very fast. This suggests to me that the kernel update is the problem, most likely the NIC driver. This motherboard has a Realtek 8112L NIC fitted.

Has anyone else had this issue and what is the best way around it other than loading the older kernel and hoping that the next update will fix it?

Under Fedora 9 everything was fine. Now, when loading web sites, about half the time, there is a pause of several seconds before the page starts with a message in the status bar of "Looking up <domain name>". Seems like a problem with name resolution. Half the time, this isn't an issue ... wierd.

I upgraded to ubuntu 10.04 lts yesterday. The upgrade went smoothly. but now I have a very slow internet connection. It is as if I am on a dial up when I have a broadband speed of 20 MB. What can I do to fix or perhaps roll-back the installation to the previous proper working state.

Intel Core i7-5500U with Intel HD Graphics.So I updated to the backports kernel and backports intel xorg drivers and I have the weirdest thing.Everything is stuttery even cinnamon desktop effects are no longer smooth. If I boot back to 3.16, everything is butter (except the screen corruption). Even my favorite wine game dropped 25% in fps.

I remember that on windows, if the cpu is too slow (pstate_min_speed), graphics is also stuttery. However, increasing /sys/devices/system/cpu /intel_ pstate/min_perf_pct even to 100% didn't do the trick. I suspect, that this measure is causing it: URL....

how to increase the performance again? I just found out, after running glxgears (with about 40 fps), that xrandr shows an available framerate of 40fps

I guess that's what makes it feel slow. Do you know how to get that back up to 60 (fixed)? It seems like the screen refresh rate set in xrandr has no effect on the problem. When I boot, glxgears runs with 60 fps and everything is fine. After a while, it drops to 40 and the whole desktop keeps stuttering. if I change the resolution with xrandr and then change it back, it goes to 60 again for a while

When using launchpad and the ubuntu daily build website it is very slow. I get 1.2mb/s normally and the speed drops quickly to 0kb/s This is the case from any version of ubuntu that is installed on my laptop.In windows it is no problem, equally there is no problem from a live cd or an install on my external hard disk. Is canonical blacklisting/slow listing my ip?

I am behind a university network but am sure this problem occurs at home .I did a clean install and had no problem until about an hour ago. When I tried to re download a project using bzr my speed instantly ropped.I had downloaded it fine a couple of hours ago. I hope that someone can shine some light on this, its very hard to work on projects if I can't download them.

I'm finding that the internet speed in Ubuntu 10.04 is over twice as slow as the speeds that I am getting in Windows 7.I've tried disabling IPv6 through Grub and Firefox but it didn't really help much.. anything else I can try?Connecting through wireless at 54 Mbps.

my computer ran on windows now is duel boot runs fine with vista internet wise (wireless) but ubuntu is very slow just like a lo of people are saying but just now i thought i will hook it up wired to modem and it is not any faster at all very confused and dont know where to go or what to do

I'm staying out at a friend's house in the middle of nowhere, and she's been complaining about how slow her satellite internet has been of late. So I decided I'd take a look. If I ping my server at home, I end up with these statistics:

Compare that to driving 70 down the highway tethered to my cell phone: I see latencies in the 3000's and out-of-order packets, but practically none get dropped. If you ramp it up to 5 ping probes a second, the loss climbs to around 75%. To me, that seems quite excessive. The interesting thing is that all the packet loss seems to be occurring on download traffic - I set up tcpdump to monitor the packets on my server during the ping test, and all but 1 of the pings to got there, so the other 25 lost packets wondered astray on the return trip. I tested it with the client directly connected to the modem (it had the public IP).

So I'm quite certain that it's the satellite link itself that is the issue here. I've attached the complete logs from the ping test for your enjoyment. Of course, TCP corrects for the loss of packets, but with a latency of 800ms, resending packets takes a significant amount of time, not to mention services like DNS that just wait for a timeout to elapse (which is usually way too long). It can take 15 seconds to load a webpage. So I guess my question is, should it be this bad? I know satellite is generally terrible, but I didn't expect to see such rampant packet droppage.

I just installed dual boot Ubuntu 10.04 on my WinXP laptop. The laptop is a Compaq v2552us.

In windows mode, the internet works plenty fast.

In Ubuntu, I can't download a single update for hardware drivers or for ubuntu (it says there are 74 though).

It starts to DL, but max speed is about 800B/s, but that only last for a couple seconds before it switches to unknown. I am connected to my wireless router via cable, can't even get wireless to work (I suspect the aforementioned hardware drivers, which is why I need this to work).

When both comps are on, the internet works fine, but when my second computer is off, my main computer has super slow internet. Sometimes it takes 2 minutes and I get "This webpage is not available", and then I refresh that and it finally loads.

I configured manually it but it doesn't works well. I set up the DHCP server on Windows 2003 so I tried to configure it with dhcp too. It gives addresses from 192.168.1.200 to 192.168.1.240 there are no PCs connected with DHCP at the moment, so my IP is only mine.

It takes a lot of time connecting to a internet web site! It's really strange because downloading a file the transferring rate is good, it takes some time starting, but it works normally. I wait almost 7 seconds after seeing a web site. All the others PC's (windows xp) can connect perfectly to network using static and DHCP. Trying with another wire in another room I've got the same result. My /etc/resolve.conf is configured with the IPs specified upper in this page.

I set up my linux router as a simple NAT router. I use CentOS 5.4. When I set up ISP proxy IP in the browser of client PC, Internet access is fast. When I remove ISP proxy IP from the browser, Internet access is slow.

ISP use transparent caching but I can use manual caching as well. Clients on my network with transparent caching get slow internet access and using ISP proxy get fast internet access.

ISP announce that we can use transparent caching or manual caching.

So, I set up my linux router with squid. I set up cache_peer TAG point to ISP's proxy IP. But the problem is the same. Using my squid proxy is slow and using ISP proxy directly is fast. All other network settings are correct.

How can I improve my internet connection using transparent caching. I don't want to set up proxy IP address on all clients.

Is karmic is slower for you all: if you're running windows ping a server on windows/ubuntu and compare. 9.10 is consistently slower for me. I've seen enough "slow internet" posts to suspect that someone screwed up bad. Everyone says it's ipv6, but none of the fixes work for me. Pretty sure it's ipv6 (or at least a dns-related problem):

I've been running Ubuntu 10.04 inside Windows 7 (demo version) for 2 weeks or so now and I really loved it. So much so that, last night I decided to burn the boot cd and put a full installation of it on the computer, instead of using Windows 7. After doing so, I started getting some small problems.

First problem was with aMSN, the webcam doesn't work anymore. It used to work when I was using the demo version of Ubuntu, but not anymore. I had to use meebo to get it to work, don't think that's a problem with Ubuntu though.Secondly, Firefox is running really terribly. Whenever I try to watch a video, it stutters REALLY bad, as if it's maxing out my CPU.

Third, I'm getting an error message whenever I start Google Chrome, it says:"Your profile could not be opened correctly. Some features may be unavailable. Please check that profile exists and you have permission to read and write its contents." It plays videos well but half time the audio doesn't work and I have to restart Chrome. (I tried uninstalling and reinstalling through synaptic, but that didn't work, the problem was still there).

Fourth and finally, the internet is just really really slow. Since the moment I installed the full version of Ubuntu it's be REALLY slow. I tried a download through bittorrent and the speeds were terrible, I ran a speed test while downloading (upload was limited to 5 kb/s) and I was still getting speeds of just around 10kb/s. So I closed bittorrent ran a speed test again and I had 1mb download and .75mb upload with 31 ping. I ran the test again and got 42 ping with same download and same upload. While I was downloading, the ping was 309. My normal speed is supposed to be 6mb download and 1mb upload

I guess version 7.0X had internet issues aswell because, when I did a google search for a solution, it turned up several results on how to fix it for 7.0X, which didn't work because the alias list didn't have anything in there. (the fix had something to do with ipv6). I tried direct connecting my internet and the speedtest results were normal, so I've concluded that it has something to do with my router. However, I don't know how to do a firmware update or troubleshoot the issue on Ubuntu. I finally decided to give up on Ubuntu and switch back to Windows 7. However, my drive is currently formatted into ext4 and I need to go back to NTFS, how do I do that? Could I just use gparted?

I'm on Ubuntu 10.04 and I'm having problems with internet speeds on wifi. I have tried the two available networks on my university campus and both of them are very slow with 10.04. I'm not having problems with Windows 7 running on these networks. Although, the wired network works perfectly fine, with normal speeds. I've looked around for help but I could not find anything specific to this problem.

so i had Jaunty installed last week with no problem. But then i decided to install winxp, erasing it. I hated it, and reinstalled ubuntu, this time lucid.However, the internet has stopped working properly. I've tried wireless and wired connections and they either dont work or will load half a web page after a few minutes. A good deal of the time the browser will time out or fail to find server.The ethernet is working, so I'm assuming the issue is with a missing driver or the such. I have 10.04 32bit installed on Gateway MD2614u laptop.

I am currently facing a weird problem, It's that the internet connection becomes extremely slow when using static IP instead of DHCP when Im connected through a cable! The local network seems okay with both, but differs when using the internet!

When I used static IP i received only one packet while when using DHCP i received all three!! Also I lost 66% of the packets when using the Static IP connection! And most importantly, the speed, DHCP connection was 8 times faster than Static IP connection!

Previously had 2 Ubuntu computers setup Computer A (192.168.1.101) <=> Computer B (192.168.1.100) -> Internet Computer B was the gateway, and it is dual boot, one drive Ubuntu, one drive XP. I'm using XP as the gateway now, but Computer A is extremely slow, virtually nothing getting through.

Have checked sysytem logs, verified /etc/hosts file, and all the network side of things. Can ping either IP adddresses from either computer. On the XP side, have modified hosts and lmhosts, and the XP computer has very fast internet connection.

Did have Commodo firewall running on the XP, disabled that, and checked that no Windooze firewall was running. Have restarted the network on both computers a number of times. Can't figure out what the problem is. It's obviously on the XP side, as when I booted to Ubuntu (previously) on Computer B, the gateway worked just fine. Have checked the whole tcp/ip side of things on XP; seems to be okay.

I have Ubuntu running on my HTPC and for the longest time all this was working fine. Now all of the sudden my Internet connection is all sorts of slow. Chrome browser, transmission bt, apt-get, all have the same speed issue. I tried disabling IPv6, changing my DNS and installing all the latest updates. Nothing works.

I bought a new Laptop 2 week ago. It works well, but internet connection ist very slow. I use cable internet speed 25Mbit/s, normal with my old Laptop (Window xp) I can DL with speeds ca.1 Mbit/s but with this new ca. 15 kbit/s (same file). too much different!!! If anyone know, how to troubleshoot this problem, please tell me. And i get a advice that i should crate a new connection using the "workgroup" model instead. I've tried to do but failed. Who knows "how to" please explain it for me.

I have installed Ubuntu 10.10 on my laptop, and the internet was very slow and kept dropping in and out for any web browsers and sometimes the Ubuntu software center. After searching the internet for a while I came across several article saying to disable ipv6, which I have done, but the issue persists

I have an old HP pavilion laptop (2005) that was useless.I installed Ubuntu 10.10 on it and it became a working computer again. It was excellent, snappy, it was as if I had bought a lower end modern laptop.Internet was working great.I did not have any complaints (in fact, I thought that a modern computer running Ubuntu would beat my so adored macbook, speed wise). For some time I had 2 efficient computer, a macbook and the hp with the Ubuntu OS. So on the last weekend of February, my internet got extremely slow on both computers. After that annoying weekend (February 28) the internet on my mac was good again,however, the internet on my linux continued to be messed up.I tried disabling IPv6 on my machine and on firefox, tried the openDNS, the MTU stuff, but nothing.I even formatted my disk and installed ubuntu again (all this using the installation CD).However, apparently the installation CD uses some of your existing configurations (for example, the layout of the close, minimize,maximize:menu buttons on the corner of windows did not go back to default). So I'm guessing whatever was messed up with the computer didn't change back to default or the previous configuration when I first installed ubuntu. To give you an idea of how slow the internet is, installing alien (terminal installation),I got low speeds of around 150B/s (no typo here, it was bites, not kilo bites) and the fastest around 5,000B/s. The fastest I got was downloading chrome at 6kB/s but that didn't last even a minute. So given that these transfer rates are obtained both on firefox and the terminal, I'm assuming it is not a browsing problem.

A thick headed solution, would probably be to install windows again to get the network configuration to "standard" and then install Ubuntu formatting the disk again (using the CD).I'm using ethernet,so,thinking it might be cable problems, I did try to use the cable that was on my mac on the machine with linux. No success there.

I've installed recently Ubuntu 11.04 and the first problem that I had was with my wireless lan card Wl-138g V2. The card was not enabled by the system, however after following one of Ubuntu's forum thread I managed to solve it, but... and there is always a but the internet speed is very low.When I had windows installed I faced the same problem and it was solved with an update in the driver, does any one experienced the same in Ubunutu? How did you solve it?

I installed 11.04 last week. Everything was working brilliantly until I turned on my laptop today. Now my wireless internet is running soooo slow. Requests take like 5 seconds, then it loads the page for about 10 seconds. Last night it was running fast.Chrome/Chromium/Firefox all run super slow. I tried turning off wireless-N and using G instead, but that didn't help. My windows 7 desktop is not experiencing the same problems in Chrome, or Firefox. I'm not sure if it's updates that I installed yesterday that didn't take until I restarted today

I replaced only my mainbord and cpu and Ubuntu 9.10 boot just fine. The only issue that I have is that my connection speed dropped from 10Mb to 3Mb. I try the connection on my laptop and it is fine 10Mb, so the problem is with the PC. What else to try before reinstall Ubuntu as a final step?

I've been using Ubuntu for a while (though I would not consider myself an "expert") and have just gone back to school. I live on campus and connect to the network through an ethernet cord. On Windows, the download speed is 1 Mb/s by default, but if you go through and configure the network card (turning off the auto-negotiation and setting the speed to 10, duplex full) the download speed will increase to 10 Mb/s, a considerable difference. So, I tried to do this in Ubuntu by opening the terminal and typing the following:

sudo ethtool -s eth0 autoneg off speed 10 duplex full and all of a sudden, my computer isn't connecting to the internet. When I type: sudo ethtool -s eth0 autoneg on it suddenly starts working again.

I had a dual install of Windows and Ubuntu working for a good week, then I reinstalled Ubuntu, completely wiping the machine. My connection is greatly reduced--updates take hours to install, but internet surfs okay.
